This invention relates to a combined push rake and hoist andparticularly to an apparatus to be mounted on a conventional farmtractor for gathering and stacking material such as hay.

An important object of this invention is to provide novel means forgathering a load of material in a hay basket or receptacle with anarrangement of elements which permit the use of pivotal supports sosuspended. as to place the load during gathering, hauling andconventional stacking forward of the center of gravity of the tractor,while at the same time such arrangement of elements permits overshootingor catapulting the load at the rear of the tractor and at a pointconsiderably to the rear of the center of gravity of the wholecombination of tractor and mounted hoisting elements.

A further object is to provide a single operating control which willtilt the basket forward or backward when in its lowest position. raiseor lower the basket to conventional dumping position forward of thetractor, raise the basket to vertical overshot position for catapultingthe load to the rear of the tractor and lower the basket from suchvertical position.

A further object is to provide such an apparatus wherein the rake orbasket comprises substantially horizontal sweep rake teeth and pitcherteeth arranged vertical thereto, and to provide automatic means formaintaining such portions of the rake or receptacle structure in normalposition until it is desired to dump the material therefrom at theforward end of the tractor.

A further object is to provide novel, easily operable means for dumpingthe material from the receptacle and for returning the receptacle tonormal position to reset such structure.

A further object is to provide novel means for automatically tilting thebasket or receptacle backwards as it approaches the vertical overshotposition, thus transferring the load in the basket from the sweep raketeeth to the normally vertical pitcher teeth which are .now horizontallypositioned.

A further object of the invention is to provide novel means forautomatically arresting the backward tilting movement of the receptaclein vertical overshot position.

A further object of the invention is to provide novel resilient saddlemeans at the forward end of the tractor on which the back or headportion of the material receptacle may rest when the tractor is moved sothat the load may be smoothly transported over rough ground.

I A further object of the invention is to provide 16 Claims. (Cl.214-140) stabilizing means which automatically come into ground engagingposition at the rear of the tractor when the material receptacle israised to vertical overshot position so as to transfer to the ground apart of the forces acting on the arms supporting the receptacle andacting within the whole structure.

A further object of the invention is to provide a structure of thischaracter wherein the elements may be so constructed and located thatthe center of gravity for the combined structure, includin thetractonlies forward of the rear axle of the tractor for all positions ofthe swing of the receptaclefrom ground to vertical overshot position,thus providing a stable and safe operating structure.

A further object of the invention is to provide for the ap lication offorce for controlling the swing of the receptacle ata relatively lowpoint on the appa atus and to have such force act in a svbstantiallyhori"onta1 plane. 7

A further object of the invention is to provide a compact receptacletrip and return assembly and mounting on which control forces may besuperimposed for tilting the receptacle separate from a tripping anddumping action. 7

of base member 51 and extends at an angle of about with base member 51in a direction nearly opposite to the base member '52, therebypermitting the forward ends of th'ederrick arms to more readily slideover the surface of the round when in ground engaging position. The:

supporting member 58 is apertured at 59 and provides a pivotal mountingfor the basket assembly generally indicated at 60 in Fig. 1.. A tubularmember 6| extending transversely to the base member 5I and weldedthereto at its right end forms a pivotal mounting on the right derrickarm for a stool to support the hay baskets head in overshot position. Onthe left derrick arm, this member 6| serves as a pivotal mounting for abasket latch lever rod, described later. Towards the outer ends of eachof the derrick arms there is secured, as by welding, an upwardlyextending guide plate 62 which cooperates with the derrick arm guards4545 of the front assembly. On the right derrick arm there isadditionally attached guide mountings 63 and 64 for supporting the tripassembly, shown in detail in Fig. 11. At the outer end of the basemember 52 an aperture 65 is provided for securing an evener bar 66, seeFigures 2 and 15. I

The right and left derrick arms, generally indicated at 50, see Figures1 and 2, are bolted to the end plates 26-26 of the derrick axle frame,

see Figure 6, which is pivotally supported by the derrick axle framesupport generally indicated at I3. A pair of diagonal sway braces 99 andSI have their lower ends bolted to brace member 51 of each derrick arm.The upper end of brace 90 is bolted at 3| to upper cross member 25 ofthe derrick axle frame-23, see Figure 10, while the upper end of brace9| is secured to the lug 28 afiixed to the pivotal cross member 24 ofthe derrick axle frame. By this mounting and bracing arrangement, thederrick arms 50 pivot about the upper end of the derrick axle framesupport I3.

Referring to Figures 4 and 5, the hay basket or sweep rake receptacle,generally indicated at 66, is pivotally mounted on the ends of thesupport arms 58 on the ends of derrick arms 58. The basket is built uparound a base framework of angle irons welded together and comprisingspaced cross members 66 and 61 which are connected by four transversemembers 68. Sweep rake teeth 69 extend transverse to and on theunderneath side of cross members 66 and 61 where they are attached bybolts at their rear end portions 69' to form the head of the basketwhich in Figure 4 is shown resting on head rest saddle 39. Pitcher teethextending upwardly and at right angles to the sweep rake teeth 69 arebolted at their lower ends to the forward edge of cross member 66.Pitcher teeth III are given additional support by rear braces 13 whichextend from about the mid-portion of the pitcher teeth rearwardly anddownwardly to the rear cross member 61 of the base frame. The basket ispivotally connected at 59 on the ends of support arms 58 by suitablepins extending through pivot plates I4 welded to the underneath side ofcross member 66, as shown by the broken away section in Fi 4.

A basket trip attachment framework, generally indicated at I5, comprisesfour upwardly and diagonally extending members 16, 11, I6 and 11' whichhave their upper ends converging and welded to a plate I9 while theirlower ends are connected to the cross members 66 and 61, as best shownin Figure 4. Plate 19, positioned to the left of the center of the haybasket, serves as an attachment for the basket trip rod to be describedlater.

A basket return lever, generally indicated at 80, has a U-shaped basemember 8I pivotally connected at its lower end at 82 to the lower end.ofthe base support 5| of left derrick arm 50. Attached to the upper end ofthe U-shaped member BI is a forwardly extending are shaped rod 82apertured at its end to receive a connecting chain 83 attached to avertically extending bracket 84 on the hay basket. This basket returnlever 89 has fixed to its rear portion an apertured bracket 85 to whichis pivotally connected the lower end of a basket return link 86 whoseupper end is attached to a basket return tension spring 8'! anchored atB8 on the left derrick arm 50. It will be noted that this basket returnlever applies force at the right of center of the hay basket, see Figure4, to return the basket to normal upon its being tripped. Force toreturn the basket after trip is also applied to the basket tripattachment frame work I5, previously described.

The trip assembly for overshot generally indicated at 94 is shown indetail in Fig. 11. This trip assembly is slidabl mounted on the upperforward portion of the right derrick arm 50 by means of the mountingguides 63 and 64, as previously described and shown in Fig. 6. This tripassembly serves to control the hay basket both for stacking operationsand overshot operation of the derrick arms. By its being slidablymounted it also serves to tilt the hay basket in response to forceapplied and released at the evener bar 66, see Fig. 2. The trip assembly94 comprises a guide shaft 95 having slidable movement in mountingbrackets 63 and 64. The upper or left end of guide shaft 95 ha connectedthereto at 96, the lower end of the connectin chain 91 leading to a slotin the overshot control arm generally indicated at 98 in Figure 1, andshown in detail in Fig. '7. Also at the upper or left end of the guideshaft 95 is affixed a transversely extending slide 99 apertured toreceive for sliding engagement spring guide or basket trip shaft I90,which is of tubular form and has afilxed to its left end a flange plateIIlI. Surrounding the spring guide I60, is a compression spring I02,whose left end bears against the end flange IIlI of spring guide I90,while its right end bear against guide plate 99. This compression springis compressed as the basket is dumped by gravity and serves to returnthe basket to normal position after dumping. Extending into the left endof the spring guide I00, is an end guide I63, in the form of a rodhaving a bracket I64 fixed to its upper or left end'and which is securedto plate 53 on the right derrick arm 50, see Fig. 1. The right end ofthe spring guide I99 has attached thereto, by means of a suitablebracket, a small pulley I05, over which is run a cable I66. One end ofcable I06 is secured in a depending lug IOI affixed to the lower orright end of guide shaft 95 while the other end is attached to adepending lug III on the slidable portion II!) of a basket latchgenerally indicated at I69. Portion III] of the basket latch is in theform of a collar'slidably mounted on guide shaft 95 and having besidesthe above 7 described depending lug III, an upstanding lug an upstandinglug H6 at its right end which serves as a pivotal mounting for a latchgenerally indicated at II'I. Latch II! is formed with an upstandinglever arm I I9 and a dog I I8 which engages shoulder I I3 on slide I I0.At the rear or left end of collar H4 is attached a guide-plate 7 +20which-is apertured to receive for sliding engagement an arc-shaped rodI2I welded to and movable with lever II9. A compression spring I22 ismounted on rod I2I and extends intermediate guide plate I29 and lever H9urging lever I I9 clockwise to hold dog H8 in locking position. At theupper end of lever H9 is pivotally connected a hand control trip lineI23 which is secured to the overhead cab structure, as shown inFigure 1. A control rod I24 has its left end pivotally connected to thelug I I2 on the slidable portion I ID of the latch I09 while its rightor lower end is pivotally connected to the plate 19 :on the basket tripattachment frame 15. When -dog H8 is released from shoulder H3, theslide I IO'slides forward on the guide 95 and allows the basket to dump,whereby spring I92 is compressed.

The overshot control arm, generally indicated -at-98, in Figures 1 and7, is shown in detail in Figure '7. This control arm is made up of amain member I26 provided with a pivot mounting plate I21 at its lowerend. At the upper end of member I26 is attached a slotted plate I28having a slot I28 which extends throughout its length at an angle ofabout 160 with main member I26. Diagonal brace members I29 and Iinterconnect plate I28 and pivot end I21 of main member I26. Thejuncture of the diagonal members' I29 and I 39 serve as a connectingpoint for the basket leveling cable I39, see Figure 2. 'I-heovershotcontrol arm generally indicated at 98 is mounted at its pivot end I21 onthe right derrick brace I I by a pivot pin I3 I.

-A pivot support for the overshot control arm' '98 is provided as shownin Figures 1 and 2. This pivot brace I32 extends from pivot pin ISI ontheright derrick brace II to the right leg I4 of the axle frame support,as shown at I 33.

Referring now toFigure 8, there is shown a detail assembly of theovershot stool and its cable mounting. Parts of the right derrick arm 56are shown here, namely, the main support arm its end supportin member59, and the pivot mounting 6|. The overshot stool, as indicated at I35,is U-shaped in form and pivotally mounted at -6I to the base member 5|.A spring I 35 has one end attached to the stool I35 at I31 while itsother end is pivotally anchored to the support element 58 as at I38.This spring I35 tends to pivot the stool I35 in a clockwise direction.Cable I39 has its lower end secured pivotally to the stool I36, as at549, and is led upwardly through guides I4! and I42 on arm 5| overbearing I9 mounted on the derrick axle support frame I3 where its upperend is secured to frame I3 at I43. The function of the stool is toprevent the basket 69 from pivoting backward or counterclockwise whenthe derrick arms are elevated to an overshot position with a load, asshown in Figure 3. When the arm 5| is down ready to pick up a load, thecable passes around the bearing I9 and pulls the stool I35 in acounterclockwise direction about its pivot 6 I, as shown in Figure l.The stool I35, as shown in Figure 1, is out of the way of head portionof the basket 60; however, if the arms are raised the cable is unwoundfrom the bearing I9 allowing the tension spring I36 to pull the stoolclockwise into position under the head of the basket, as shown in Figure3. This prevents the basket from tippin backwards and dropping the load.

A cab shield generally indicated at I45, see Figures 3 and 4, is made upof a framework and forms a barrier over th driver for his protection.

It comprises two for ardly extending legs I46 and I41 having-their lowerends bolted to the right and left derrick braces II and I2. The upperends of these-legs are interconnected by a cross member I48 which isfurther supported by braces I49 and I 50 extending diagonally to each ofthe legs I46 and I41. A pair of top cross members I5I--I5I havingrearwardly and. downwardly extending end portions I5I' extend from theupper ends of legs I46 and I41 to plate I52 at the middle of crossmember I8 on the derrick axle frame support I3.

Overshot control chains, as indicated at I5-3-I53 in Figures 3 and 4,have their lower ends connected to a flange I54 attached to the cab I45,while theirupper ends are connected to a spring I55 which has its upperend pivotally connected to a lug I56.depending from main member 5I ofderrick arm 59. When thederrick frame 23, see Figure 10, at 29 on itstop cross member 25. Two steadying braces I62--I62 are pivotallyconnected at their lower ends to the lower end of upright member l5l atI63. A ground engaging shoe in the form of a plate whose rear end isbent upwardly is welded to the lower end of upright member I6I of thestabilizer. V

The power cable system is generally indicated at I19 in Figure 13. Apower reel MI is mounted at the forward part of the tractor on a supportframe I12 which supported b cross member 33', see Figures land 4. Fromthe power reel the cable passes to the front right side of the tractorover pulley I13, rearward to and over pulley I14 pivoted to evenerbar66, see Figures 1 and 2, thence forward to the front lower side of thetractor over pulley I15, across the front of the tractor over the leftlower pulle I16, then rearward to and over pulley I11, pivotallyattached to the lower pivot point 55 on the left derrick arm 50, thenceforward to I18 on the left derrick brace I2 where it is dead ended.

The overshot control arm 98, see Figures 1, 2 and 3, is pivotedcounterclockwise about its pivot I3I by means of a pull applied to cableI39. Cable I39 is led over a sheave I89, pivotally mounted on the upperend of right leg I4 of derrick axle frame I3, to one end of evener bar66, pivotally mounted on the end of support member 52 of the rightderrick arm. A pulley block I14 is pivotally connected to the other endof evener bar 66. Force applied through the cable system I10 connectedto block I14 first tends to pivot the evener bar 66 about its pivotalmounting into a substantially horizontal plane in which the appliedforce lies. As a pull is applied to the lower end of cable I39, itpivots overshot control arm 98 counterclockwise. Further application offorce will now swing the derrick axle frame counterclockwise and in turncontrol arm 98 will also be rotated counterclockwise.

The first force applied to rotate evener bar 66 is transmitted throughthe control arm 93, the slidably mounted trip assembly 94, basketcontrol cable I24 which tilts'the basket backward on its pivotalmounting. As this first application of force to the evener bar 66. isreleased,

the basket will tilt forward under the influence of gravity. This actionof tiltin the basket 60 is particularly useful when the basket is in itslowest position as in Figure 1. By this tilting movement of the basket,its sweep rake teeth 69 may be moved into and out of ground engagingposition. It is to be noted that the same force means which tilts thebasket 60, a described above, is used to swing the derrick framesupporting the basket. Thus, one single control of the applied force,generally indicated at I10, is used to tilt and swing the basket.

In Figure 15 there is shown a modified form of evener bar at I8I whichhas one end pivotally mounted to the end of the right derrick arm 50. Asheave I82 is pivoted intermediate the ends of evener bar I8I and hasled over it cable I30, the lower end of which is attached to pulleyblock I14. An adjusting chain I83 has one end connected to pulley blockI'M while its other end is adiustably connected to the free end ofevener bar I8I. as at I84. As a pull is applied to the pulley block I14,it first takes up on cable I30, and then the connecting chain I83 takesover to apply a pull to rotate the derrick arm 50.

Referring now to Figure 14 there is shown diagrammaticalh the wholestructure. While a mid-position of swing of the derrick frame isOperation Power is supplied through a conventional power take off andclutch, not shown, on the tractor to drive the reel III. A brakegenerally indicated at I85, see Figure 1, controls the power reel whenlowering the derrick frame. While the power reel has been shown mountedat the forward end of the tractor, a power reel mechanism can be mountedat the rear of the tractor on suitable support frames attached to thedraw bar.

When it is desired to use the rake as a sweep rake, the basket orreceptacle 60 is tilted forward under its own weight by allowing reelIII to pay out cable. This permits the evener bar or take up 66 to pivotclockwise, and cable I30 leading to the overshot control arm 98 ispulled forward by the pull exerted through the basket's forwardrotation. The control cable I24 leading from the basket control arm Ipulls the slidably mounted trip assembly 94 forward. Basket trip I09 isat all times locked unless it is desired to dump a load from the basket.The downward sliding movement of the trip assembly 94 is transmitted tothe overshot control arm 98 by means of chain 91, connected at the topof the trip assembly, and the connecting link 91 the latter of whichslides in the slot I28 on the overshot control arm. Cable I30 which hasbeen slackened allows the control arm 98 to pivot forward. To tilt thebasket backward, it is merely necessary to apply power to the cablesystem I10 and the evener bar 66 exerts a pull on cable I30 to reversethe pull on the overshot control arm 98.

To raise the derrick arms, power is continued to be applied on theevener bar 66 which pulls on the lower end of the derrick frame arm. Asthe basket or receptacle is elevated, link 91 continues to slide up theslot I28 under the pull exerted by the basket. The overshot control arm88 pivots counterclockwise in response to the swinging movement of thederrick arms and frame. Thus, as the derrick frame is elevated,

the basket is maintained substantially level as the action of the slidelink connection 91 permits the basket to continue to tilt forward tocompensate for its upward swing on the ends of the derrick frame. Theupper limit of slot I28 is reached when the basket has been elevated toabout two thirds of the way to a vertical overshot position. For anyposition up to this twothirds position, the basket may be dumped forwardof the tractor. Dumping takes place when the trip control cable I23 ispulled to release latch I09. This permits slide III] to slide downwardlyand allow the basket to dump. As it slides down.

, it takes up on cable I06 which runs through pulley I 05 on the end orthe trip return rod I00. sprin I02 is compressed and after the baskethas dumped its load, the spring tends to return the rod we to" itsnormal position, thus pulling on the basket control cable I to returnthe basket. To assist the basket to return to normal arter dumping itsload, the trip return mechanism 80. see r'lgure 5, also exerts abackward pull on the basket.

If it is desired not to make a forward dump with'tne load, as justdescribed, but to overshoot the load to the rear or the tractor. thecasket trip I09 is allowed to remain in locked position while power 18continued to he applied to the derrick arms to elevate them to avertical position. by spee ing up on the swing or the derrick arms asthey ap roach the vertical. me load may be given more momentum to throwit runner to the rear of the tractor. as the DaSKGE approaches thevertical OVCISBOIG position, a pull is eilerted on came 124 to up theoasaet iurther backward so that the load will rest on the pitcher teeth10, see meme 3. 'lms pull on came |2 results on shoe mix 97 havingreached its upward travel at the end of slot I29 on the overshot controlarm 98 and the pull exerted by the backward pivoting 01. the control arm98 which swings under the mnuehce oi: the derrick rrame.

To prevent the basket 60 1mm tilting fully backward and spilling theload, overshoot stool Mu swings into position under the head of thebasket and arrests its backward rotation. This stool is pivoted intosupporting position by me man exerted by spring I36 to rotate itclockwise. As the basket is lowered this stool rotates counterclockwiseunder the influence or the pull on caole I39. when the basket is in itslowest position, the overshot stool H0 is fully rotated Out of the wayor the head of the basket and permlts the basket to be tilted.

As the derrick rrarne approaches its vertical overshot position, slackis taken out of arresting cables I53 and the tension springs I55, seeFigure 3, tend to snub the backward swing of the derrick frame. At thesame time, the load on the derrick frame is automatically transferredfrom the tractor to the ground through the stabllizer generallyindicated at I60. Arm m which is attached at its upper end to a midpoint on the derrick axle frame 50 now extends substantlally verticaland through its foot plate IE4 at its lower end, transfers the load tothe ground.

While a hay basket or receptacle has been shown with this loader, a.scoop, such as a manure basket, can be substituted for the basket. Theform and arrangement of parts provides a loader which is stable and safefor all positions of placing the load forward or overshooting it in therear of the tractor. The loader is easy to operate and. has a minimum ofcontrols for the operator to handle.
